not sure if this will q be beating a dead horse or not but here goes:

any of you experts consider using the 300zx (z32) rods ? please share your thoughts on this.

If my memory serves me correctly, they are way too long, and with the price and availability of the rb30 stuff, there would really be no need

gotcha!

i should do the math first. the 300zx rods is 1.8mm longer than the rb30 (6") rod.

even with the combination of the 300zx rods w/ the rb25det pistons it still protrude above the deck.

hmm...a thick headgasket may solve it. the availability of the 300zx here in he States are abundant and so cheap.

the GM SBC rods option is also dirt cheap: 250.00USD (266.010 AUD); make this also a nice option i'm itching to dive into.

hey im buildin my rb30det atm and im tryin to sort an intake setup 4 it. Using a rb25de head i was considering using a factory intake but have the plenum modified to front facing. But recently i heard that this mod can lean out the 6th piston or something. Any opinions or advice would be great.

Thanks for those pics fellas, ive been tossin up which way my piping will go.

Either way looks good with dan's having slightly more bends?

also what ex manifolds are you guys using (dan and sir racer)

cheers

If you are after a quality exhaust manifold i highly recommend 6boost or Extreme Turbo Manifolds (ETM). I am using an ETM item and my mate is using 6boost; both work of arts :teehee:

Did you cut a hole where the battery used to sit?

My previous skylines have been defected for cutting holes, DOT inspectors said it weakens the crush zone of the body and all piping should go through factory holes or be plumbed around the body.

My current rb20 piping is done this way.

I wish the service was the same quality. ;)

For some reason Leigh (ETM) quoted me higher through these forums, and $150 lower (same car, same manifold) on CLT forums under a VLT orientated username.

They both take months to reply to pm's and email, thats if they do...

The prices these days are a bit steep for a street car.... I'll be making my own. :bunny:

hi guys, not posted for a while.. right section now, :D after some advice as usual.. my rb26/30 has now done 2500 miles no problem whatsoever, but is under turbo,ed.

specs is as follow,

rb30 block decked bored to 86.5mm

spool rods, cp forged slugs.

acl bearings,arp bolts everywhere.

trust sump

1000cc injectors, twin in tank tomei fuel pumps.

hks drag 4" intercooler..

1.0 tomei headgasket.

jun stage one cams 264/272 9.7mm lift.

full extreme turbomanfolds kit using a gt35r 1.06 rear 4" dump

car made 680bhp 645lbs @ 5500rpm but drops off after 6500rpm,s

pm,ed leigh ref replacement kit as i have a buyer for mine.

thinking of going t4 flange and twin scroll.

leigh suggested gt4088r or 4294r

not sure what rears to use on either, or spooling times on either too?.

looking for 750-850 bhp @ the fly..with a good spool.

cheers bernie.uk

Nah R33 has battery in the boot from standard, But I had to remove the windscreen washer bottle that I will replace with a alloy surge/washer bottle when the wallet permits

There is a region below the washer bottle where the GTR piping is run through as standard and the rail is exactly the same in a 33 GTSt. It even has the shape stamped. Cutting the hole and finishing with a little reinforcing is generally fine. Do a good job, tell them it is factory and if they want proof get a mate with a GTR and show them or take photos.

Was wondering if many have used the rb30 gearboxes? I bought mine with the block im using for my 30 build and iv heard heaps about the gtr and 25t g/boxes bein really strong but not so much is said about the rb30 boxes. So any advice or opinions on their strength? also what are the ratios like? Cheers.

    • Per Mark Roberts of Sonictune: Mark Robert Author At this time, no. No ETA either 2016-17 models. You will be able to purchase and install a 2018.5+ TCU though   TCU purchasing and pricing info! As we near the release of TCU tuning, I am going to answer some questions I get asked often.   What do I need for TCU tuning? At this time, you will need a 2018.5+ TCU to be able to tune. If you have a 2016-to early 2018, you will need to replace your TCU with the newer version. One good way to know if your TCU is good is if you have auto upshift in manual mode in 1st gear around 6500 rpms. If your manual 1st gear goes to 7k rpm and will hit the rev limiter unless you shift, you have the older TCU.   Why do I need to buy another ecu license/phone flash if I already have it on my ECU tune? The TCU is its own computer module. It is completely separate from the ECU. Because of this, you will be required to purchase a TCU license and, if your tuner has it, the phone flash license required to tune it via phone/bluetooth.   Do I need TCU tuning? TCU tuning is NOT required. However, the faster your setup, the more it will assist in track and dragy time consistency.   If I’m ECU tuned by (tuner A) can I get my TCU tuned by (Tuner ? Yes, since it’s a different module and a completely separate flash, you can have two different tuners. However, it is highly recommend that you have both tuned by the same tuner. For me, my TCU tuning will directly complement my ECU tuning style and features and running my ECU and another TCU or vice versa MIGHT cause some issues. At this time and for the foreseeable future, I will only be tuning my current ECU tuned customers TCUs.     I have a SYVECS AWD controller. Do I still need it? Yes! The AWD controllers main job is to control your AWD system. However, with TCU tuning, you will no longer need the auto-shift function as that will be done through the TCU. The AWD controller will still be very beneficial for racers looking to maximize traction on the launch.     Shift schedule changes: holding gears longer at lower pedal input as well as max shift rpm changes. Please note, the new ECU race rom coming out will address 90% of the shitty drivability issues these cars have through custom maps from myself and Racebox—as well as others I am sure.   Increase shift speeds: as seen in the videos I’ve been posting, the TCU shifts much faster once tuned.   Increased shift pressures: as also seen in the videos, much firmer full throttle shifts.

    • The fancy pants red shock tower brace is finally incoming from MX5 Mania, getting it shipped from 'Merica has been a long and problematic process, and GWR, the 'Merican supplier will not ship directly to consumers outside of the US, Mania basically had to order a heap of them, the colour choice was silver, or red, and we all know anything red adds 5 killerwasps of dynotorques..... Whilst it does fit over a 2.5, and I've seen a few photos and videos of it being installed and fitting, google also says it might get real close to the FAB9 intake front runner, people in the US says it does fit with the FAB9 intake, except for one person who said it slightly touched.......so there is that.....LOL..... As it seems that I am the first in AU to have this combination of parts there's no local knowledge about fitment, so I'm just a willing guinea pig in this endeavour, I'll cross my fingers and toes and hope for the best In other news, I ordered stuff from China  on the same day I ordered the 23° silicone bend from Victoria, the stuff from China arrived a day ago, the 23° silicone bend is still travelling around Australia thanks to Australia Post, and "may" be here next week
    • Very good news...I contacted Racebox about it last night. My car is a 2016 so remains to be seen if it is compatible, requires a TCU swap, or is impossible.
    • What ECU are you running? This is probably the biggest question. If it's a PowerFC, I'd probably change the ECU and get something newer that will handle the injectors in a nicer way.
